Veteran Broadway star Patti LuPone has been left "greatly upset" by reports she has fallen behind on her tax payments, accusing California state officials of making a "mistake".The actress/singer recently had a $9,983 (£6,655) tax lien filed against her in the state of California, but she insists she's up-to-date with her accounting and doesn't owe the state anything. Her publicist tells the New York Post, "It was a mistake on their part. It is totally not true that she owes the state that amount in taxes. The taxes in question were paid in full in 2007 when they were deducted from Patti's payment at the time of a performance. It's been sitting in the state's coffers since then. "This item has caused great upset to Patti, who is meticulous about paying her taxes."
